Get the Latest on Abdomen and Pelvis CT Scan Codes

Computed tomography (CT) uses computer imaging and multiple, narrow beams of X-rays to produce thin, cross-sectional views or images of various body layers. These images allow visualization of soft tissue, as well as bones, making them useful for evaluating a wide range of conditions.

CT imaging of the abdomen and pelvis frequently are performed together during the same encounter. The combined services are useful for evaluating a large number of conditions, including abdominal and pelvic pain; infections such as appendicitis or diverticulitis; inflammatory processes such as ulcerative colitis; and cancers of the colon, liver, kidneys, pancreas, and bladder. Combined CTs of the abdomen and pelvis also are performed to quickly identify internal injuries in cases of trauma.

During CT of the abdomen, the organs visualized include: the liver, spleen, kidneys, pancreas, the top half of the large intestine, the small intestine, and the superior aspect of the ureters. During a CT of the pelvis, the organs visualized include: the remainder of the large intestine, the small intestine, and ureters, as well as the bladder, uterus, and ovaries.

Combined Services Call for New CPT® Codes

Prior to 2011, two CPT® codes had to be selected to reflect the combined services when CTs of both the abdomen and pelvis were taken during the same encounter. Because of an increased frequency of these services performed during the same encounter, the American Medical Association (AMA) developed three new CPT® codes for 2011 that reflect current practice.

Use these codes for a CT of the abdomen alone:

74150 Computed tomography, abdomen; without contrast material

74160 Computed tomography, abdomen; with contrast material(s)

74170 Computed tomography, abdomen; without contrast material, followed by contrast material(s) and further sections

Use these codes for a CT of the pelvis alone:

72192 Computed tomography, pelvis; without contrast material

72193 Computed tomography, pelvis; with contrast material(s)

72194 Computed tomography, pelvis; without contrast material, followed by contrast material(s) and further sections

The following codes should be used only if both the abdominal and pelvic CT are performed during the same encounter.

74178 Computed tomography, abdomen and pelvis; without contrast material in one or both body regions, followed by contrast material(s) and further sections in one or both body regions

The AMA includes a table in CPT® 2011 (see Table A) to help you determine the correct code.

Table A illustrates that CPT® 74176 should be used only if both studies are done without contrast. Use CPT® 74177 only if both studies are done with contrast.

Code 74178 should be used in two situations:

One or both studies are done without contrast, followed by contrast material(s) and further sections.

One study is done without contrast, while the other study is done with contrast.

Scenarios Help Show Correct Coding

Example one: A 34-year-old male presents with 48 hours of lower abdominal and pelvic pain. The patient also has a low-grade temperature. His physician orders a CT of the abdomen and pelvis without intravenous contrast. The radiologist supervises the process of providing the CT, and then interprets the images acquired. He also dictates a report of his findings. The radiologist should report 74176.

Example two: A 48-year-old female presents with flank pain and persistent gross hematuria. The patient’s urologist conducts a cystoscopy and is unable to identify the cause of the patient’s symptoms. He orders a CT of the abdomen and pelvis without and with intravenous contrast. The radiologist supervises the process of providing the CT, and then interprets the images acquired. He also dictates a report of his findings. The radiologist should report 74178.

Coding tips to remember:

If both a CT of the abdomen and a CT of the pelvis are performed during the same session, use one of the new codes that describes that combination of services (74176, 74177, and 74178).

Refer to the table provided in the CPT® book to determine the correct code.

Report 74176, 74177, or 74178 only once per session.

Codes 74176, 74177, and 74178 can never be reported together with any of the codes for CT of the abdomen alone (74150, 74160, and 74170), or CT of the pelvis alone (72192, 72193, and 72194).

With Respect, I read the charges for services while I was waiting to be seen and very impressed. However, when I got my statement,I was surprised and couldn’t believe my eyes. The test cost $1,400.00 and adjustment $ 1,191.67, whatever that means. Please explain through e-mail, as I will be gone for the next two days. I will send a check after I hear from you.
